| Research Abstract |
In order to clarify the characteristics of traffic flow on winter road surfaces,1)some features of reaction time, potential collision, and shockwave were compared with those on summer roads using the car-following data on actual roads. 2) An inverse method of estimating traffic situation and traffic demand on real time was developed by integrating the API module into unscented Kalman filtering. 3) A dynamic travel time prediction model that implemented the above achievements based on feedback concept was developped and justified with the precision.
